HYDRAULIC TANK ASSEMBLY (CONT)
Apply pipe sealant compound to the all male pipe threads of hydraulic fittings,
using only enough compound to coat the threads. Do not allow compound to
enter a component/fitting or the compound may restrict or block fluid passages
and damage to equipment or equipment failure may result.
Note positioning/orientation of fittings on the illustrations. It is important to have
the tightened fittings positioned as shown so that hoses are not too short and
fittings do not interfere with one another or damage to equipment may result.
If removed, apply pipe sealant to threads of pipe plugs (22). Remove cap/plug installed in bottom of hydraulic
tank (1) and install pipe plug (22). If removed, install filter (para. 4-91).
Apply pipe sealant to all threads of pipe plug (21). Remove caps/plugs on hydraulic tank (1) and install pipe plug
Lubricate two preformed packings (20) with petroleum jelly. Remove caps/plugs and install two preformed
packings (20) and sight indicator (19) onto hydraulic tank (1) and secure with two nuts (18).
Remove wiping rag and install gasket (17) and access cover (16) onto hydraulic tank (1) and secure with six
washers (15) and nuts (14).
If removed, install filter (13), gasket (12), and filler neck (11) onto access cover (16) and secure with six screws
(10). Install filler cap (9).
Install six moldings (8) and two retaining (protective molding) straps (7) onto APU frame.
Install hydraulic tank (1), slant bottom of tank rearward, and set into place on APU frame.
Install four nuts (4) onto two clamp bolt assemblies (5). By hand, thread four nuts upward onto clamp bolts
Install two clamp bolt (protective molding) assemblies (6) into position on hydraulic tank (1). Install two clamp bolt
assemblies (5) over clamp bolt (protective molding) assemblies (6) and use one person to hold in place over
mounting holes on APU frame.
Install four lockwashers (3) onto two clamp bolt assemblies (5); then, lower two clamp bolt assemblies (5) down
onto APU frame.
